My class is joining the glass explorer program in two school days. Needless to say the excitement level in my room right now is pretty high. To prepare the students for the Do Now I had them scan the following AR trigger that took them to a Tellgami. The Tellagami told them that I was going to play a 30 second video clip for them about Google Glass Games — their job was write down as many geometry vocab words they could associate with the games. Many of the Google Glass games involve shapes like circles, squares, and hexagons. Here is the Google Glass Game clip that I used with the assignment.
I used this in my high school Geometry class, perhaps you could use it in your own learning environment.
